Let’s take a deeper look so we can understand its relationship to a skeleton key.įrom the outside, a warded lock looks like a standard pin tumbler lock. That was a quick look at the warded lock and key. The bit and its key wards are the only part of the key that engages the locking mechanism of a warded lock. Some complex patterns have their own names: Box of Wards, Bridge Ward, Hook Ward, Sash Ward, Solid Ward and a Wheel Ward. Key wards are the cuts in the bit that allow the key to pass the warding within the lock. There may be more than one bit that extends off the stem.
